I feel it was lacking feedback on the weapon switch, since it's all about throwing the right stuff at the right target, it felt a bit random to have a certain weapon, align to your target, throw it but the wrong things comes out because it switched without your realizing.
I get that's the point of the game, but there was no real indicator of the timing of the switch, so it mostly felt like things happening while my focus was on the top of the screen. Anyway, the idea is cool, the art and the vibe of the game is great.
